The Naboo Tilca virus was a disease created by Brese Nu, a mad scientist born on Naboo. It was particularly deadly to Force-sensitives, but had the same affect to most. No known lifeforms were immune to it, which made it dangerous. It often changed a persons' skin tone and hair color, even adding yellow marks, similar to a Pantoran's, on one's face. Very few survivors are known. The cure was an exchange of blood from one person to another of the same kind. However, it was possible if one species had the same type of blood type as another species to cure someone that way.
